I had the same problem for my TV which was model number: 42PF9631D/37 and I went to get the software update at http://www.p4c.philips.com. Type in your model number, then click on the right model. Then click on software & drivers in the left column. Then download the correct software update to a flash drive. The flash drive must be completely empty except for this file. Then unplug your TV, and plug the flash drive into the USB port. Plug your tv back in, and the software update will upload. It fixed my TV instantly.

this sounds like a dmd board problem. these are digital modules attached to the light engines usually. samsung, rca, hitachi, have shown similiar symptoms. some units have capacitors on the boards that can be replaced, but these are dual-layer pcb's that are tough to unsolder without proper soldering iron temperature and good small gauge solder-wick. or solder pump tool. the electolytic caps. are usually 1000uf / 10v, 330uf / 10v, or 470uf / 10v. alot of the time the capacitors will "vent" or swell-up on top which helps spot faulty component. we always increase voltage rating to 16v-25v for more reliable operation. always use 105 degrees high- temperature replacement caps.

oh boy, that sucks, time to head to the local electronic repairs store. or if you still have the warranty then take it back and make a stand!

SOURCE: Toshiba 40" turns on for a few seconds, then turns off. No picture!

Consider having it repaired as it should be in warranty.
